China Launches Shenzhou-23 With First Year-Long Mission
One astronaut will stay in orbit for a year to test microgravity effects and support China’s lunar mission plans, officials said.
- China launched embryo-like structures made from living human stem cells to its Tiangong space station on May 11, becoming the first nation to send 'human artificial embryos' to space to study microgravity and cosmic radiation effects on reproduction.
- Establishing permanent human presence on the Moon and Mars requires solving a critical challenge: reproduction in space, as cosmic radiation and microgravity pose serious risks to embryonic development and sperm cell function.
- Researchers from the Chinese Academy of Sciences designed two artificial embryo models representing 14-to-21-day development phases: a peri-implantation model mimicking embryo attachment to the uterine wall and a peri-gastrulation model showing cell reorganization into tissues and organs, with samples developing for five days before freezing.
- Researcher Leqian Yu at the Chinese Academy of Sciences' Institute of Zoology stated 'This is not a real human embryo and does not have the ability to develop into an individual' but 'can serve as a model for studying early human development,' adding 'The experiment is going very well.'
- Identical embryos grown simultaneously in Chinese laboratories will serve as controls when space samples return to Earth, with results potentially reshaping humanity's ability to establish self-sustaining colonies on the Moon and Mars; parallel experiments with zebrafish and mouse embryos strengthen comparative findings.

China Launches Synthetic Human Embryos to Space Station
Will humankind colonize other star systems, spreading life to distant worlds? Or more locally, and realistically: will we ever establish settlements on Mars or the Moon? Before we even consider stuff like huge generation ships, we have to look at our biology. Can our fragile forms reproduce in space, allowing our off-world outposts to sustain themselves? That’s what Chinese scientists hope to find out. This month, China sent a batch of synthetic…
Can humanity reproduce in the weightlessness of space? Chinese researchers investigate embryos on the space station for this purpose.

China Sends Artificial Human Embryos to Space in Reproduction Experiment
Synthetic human embryo. Credit: lunar caustic / Wikimedia Commons / CC BY 2.0 China launched the world’s first experiment involving human artificial embryos in space this month, marking a significant step in research on whether people can reproduce beyond Earth. The structures, built from human stem cells, arrived at the Tiangong space station on May 11 aboard the Tianzhou-10 cargo spacecraft. The craft lifted off from the Wenchang Space Launch …
